TANGENTS
A line is tangent to the circle only if it is perpendicular to the radius drawn to the point of tangency
Solve for x.
BC is a radius of Circle C AB is tangent to Circle C
x2 + 322 = (x + 16)2
32x = 768x = 24
Solve for x.
BC is a radius of Circle C AB is tangent to Circle C
x2 + 562 = (x + 32)2
64x = 2112x = 33
Solve for x.
BC is a radius of Circle C AB is tangent to Circle C
x2 + 992 = (x + 81)2
162x = 3240x = 20

TSRS If two segments from
the same exterior point are tangent to a circle, then they are
congruent.
